No solution, but what video editor is that?

It is probably more a video editor factor than Gimp. I can add a png to OpenShot in linux with no problems but other (old) editors sometimes required a particular type of color space.

I am reasonably sure it is a video editor problem but you can try again. When you export your image as a png untick all the options as: https://i.imgur.com/Z0zAz4N.jpg

Probably not going to make any difference, try an alternative video editor, for simplicity Avidemux will overlay a logo into a video. example: https://i.imgur.com/d6z5yXL.jpg There are versions for both Windows and linux. Looks like this. Works ok here, no borders on playback.

I do not use Instagram (or social anything ) so I can not comment on how they render video.
